    Notes: As a preliminary step in the development of improved bred varieties an examination has been made of the factors which contribute to the success or failure of white clover (Trifolium repens) in hill land reseeding. Severe restrictions are placed on clover performance and N fixation in many hill areas in Britain by the poor climate, the low pH and exchangeable base status of the soils and the low frequency of effective indigenous Rhizobium strains.Agronomic solutions to some of these problems exist, but experience in mid-Wales suggests the need for new bred varieties with improved adaptation to the prevailing conditions, particular attention being directed to the limitation of N fixation by low soil temperature.

    Notes: Swards based on a mixture of SI 70 tall fescue and S215 meadow fescue were very early in spring, gave high yields for conservation in mid-season and, rested from mid-August, gave good grazing in November-December. Under this treatment, the tall fescue assumed dominance, and the swards were persistent and remained productive. The digestibility of the tall fescue swards was always higher than that of swards based on cocksfoot with which they were compared. During spring and autumn the former sward was better grazed by stock, but the position was reversed in mid-summer. Cattle grazing tall-fescue-dominant swards made better liveweight gains than those grazing cocksfoot swards during November-December.

    Notes: The distribution of natural and cultivated grasslands in relation to climate and the use of various indices and diagrams in studies of crops and climate are discussed. Attempts to establish simple linear relationships between yield and weather components have been disappointing. Studies involving light, theoretical considerations of productivity, adaptation of herbage plants in relation to climatic origin, etc. have proved more useful. Problems involved in extending the work conducted under controlled conditions to the field, are stressed. Particularly important is a better characterization of the environment prevailing in and immediately above swards of different types. The importance of winter survival in Britain is discussed.

    Notes: The botanical changes in a wet (Molinia) and a drier (Nardtts) upland pasture that followed a single defoliation by a forage harvester are briefly described. Without fertilizer the bare and litter-covered areas were soon recolonized by the original dominants; with lime and fertilizer the recolonization was mainly by Agrostis spp., even when Agrostis was a minor element in the original sward. These changes were markedly accelerated by the forage-harvester treatment. The results of surface seeding after the forage-harvester treatment are compared with those obtained after rotary cultivation. Contrasting moisture regimes and competitive thresholds led to considerable differences in sward balance and in establishment of sown species, and seeding was successful only on the wetter site. Too rapid regeneration of undesirable remnants was prevalent, but this and other hazards are related to the uneven deposit of litter left by the forage harvester; thick, slowly-rotting accumulations inhibited the redevelopment of rapidly-growing species and germination on seeded areas.

    Notes: Because in the past the main emphasis was placed on arable farming, grassland husbandry has played a minor role in East Anglia. Now the increased efficiency exercised in the arable farming of the area is being applied to the grasslands. The main trends are discussed.

    Notes: Opinions vary among research workers, grassland husbandry advisers and farmers alike as to the value of cocksfoot (Dactylis glomerata) as a herbage plant both with regard to its quality for the feeding of livestock and its ability to build up soil organic matter reserves. An attempt is made to assess the value of this grass in agricultural practice, to place in proper perspective its use over the past few decades, and to indicate where its greatest potential lies.

    Notes: A study was made of the agronomic behaviour of 18 grass varieties, surface sown, after burning an upland heath community dominated by Calluna vulgaris. Complete exposure of the soil surface, the absence of competition and favourable moisture conditions provided excellent conditions for establishment. Despite this, sward development was slower than at any other site studied, and 18 months elapsed before satisfactory sward densities, and consequently a reasonable level of production, were achieved. In contrast, white clover developed vigorously from the outset. The red fescues, cocksfoots and S170 were the most promising, while the performance of most varieties was affected by one or more hazards such as frost-heaving and summer drought. The latter aggravated the tendency of some of the varieties to produce a profusion of flowering stems and, with few exceptions, considerably reduced the colour and vigour of the herbage.

    Notes: Two deep peal deposits, one in a high-rainfall area, were surface seeded with a number of grass varieties. Their sward development and general agronomy are described. Differences in performance are associated with moisture supply and severity of winter conditions. Tall fescue, red fescue and timothy gave good results at both centres.

    Notes: The performance of livestock, on winter grass was studied at eighteen sites in England and Wales from 1957 to 1960.Beef cattle generally gained weight while grazing winter grass. They invariably did better than similar animals overwintered on the normal feeding regime of the farms concerned.At 8 centres winter grass was utilized by dairy cows. Calculations indicated that the grass provided a valuable portion of their feed.The general condition and health of livestock grazing winter grass were satisfactory at all centres.Damage caused by poaching was largely prevented by controlled grazing.The production and utilization of winter grass had no adverse effects on sward recovery in the subsequent spring.

    Notes: The effects of management on the production of winter grass wen studied of 47 site England and Wales from 1954 to 1958.Cocksfoot swards provided better grazing during December and January than perennial ryegrass. The best treatment for winter-grass production from cockfoot swards was to rest from mid-August, giving un application of 52 lb of nitrogen per acre at this time.Perennial ryegrass produced relatively high yields if rested from early September, but the herbage should be grazed before the end of November because of the risk of it rotting.Cocksfoot herbage in normal swards lost more weight from December to January than cocksfoot sown in wide drills.Local Factors, such as aspect, altitude and sward vigour, were generally more important than latitude in determining level of yield in December. but there were greater lovsess of dry matter from December to January in the north than in the south.
